Percy Jackson, The Son of Gaia (Percy Jackson Fanfiction)

The Great War is over, and peace settles in both camps. Nothing much is left of both camps, and only few survived the War.
But too soon, Gaia has found a new weapon, and using it, she awakens, fully, with all of the Titans, Giants, and every other monster imaginable fresh, renewed and revengeful at her command. Tartarus sides with her, letting out every monster out of his domain, and many more are joining. Another Great War is starting, weeks after the first, and there is no one to stop them from upturning the Olympians.
And if that's not bad enough, Percy Jackson, the strongest demigod of all, sides with Gaia. And he is not Percy anymore.
How can the two camps survive with such a strong force at their heels?

IMPORTANT NOTE: THIS IS WRITTEN AFTER HOUSE OF HADES. ALL INFO ON BLOOD OF OLYMPUS IS NOT, I REPEAT, NOT, APPLIED HERE.
FIRST FEW CHAPTERS ARE REALLY, REALLY, REALLY BAD BECAUSE I WAS TRYING OUT DIFFERENT WAYS TO WRITE
THE CHAPTERS AFTER THE FIRST FEW GET BETTER :DDD
Also, when I first worote this fanfic, I typed "Gaea". Later on, I changed it to "Gaia", but there might still be some errors where it is still "Gaea". Just ignore it.
